A small mobile phone based on the Taishan School

Overview

I designed a small mobile phone based on the Taishanpai
screen, completing my first embedded Linux project with JLCPCB. This project started with setting up the compilation environment, compiling the SDK, learning common Linux commands, understanding the Linux device tree and how to modify it, and then selecting and debugging the screen. This project used a 3.1-inch MIPI screen, and the touch function was tested according to the manufacturer's touch chip datasheet. Because the Taishanpai screen interface differed from the selected screen's interface, an expansion board was designed. This expansion board, in addition to ensuring normal screen connection, added a microphone, speaker, and onboard backlight. Finally, the official 3D casing was printed to complete the assembly of the small mobile phone.
